To all d lzom. it may concern: 1

ie it known that we, WILLIAM ISHAM and FRANK E. Mum-2n, citizens of theUnited States, residing at Butternut, in thc county of Montcalm andState of Michigan. have invented certain new and useful Improvements inHmid-iulvcrts and Bank-Retainers; and we do doclnrc the following to bea full, clear, and exact dcseri ption ol' the invention; such as willenable others skilled in the art to which it appertains to make and usethe same. v l

This invention relates to improvements in combined road culverts andbank retainers.

.lh 0 object of the invention is to provide an improved road culvertcomposed of separable interlocking sections by means of which theculvert may be readily set up in position for use.

A further object is to provide an adjustable bank retaining plate orwall adapted to be, secured to "and used in connection with theculvcrtto protect the bank or sides of the roadway at the ends of the culvert,means being provided whereby. said retaining plate or wall may beextehded to any desired length or height and at any desired angle. i i

1 With the above and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangementofparts, as will be hereinafter descl'ibcd and claimed.

In the accompanying drawings:Figure 1 is a front, vicwof the a culvertand bank retainer constructed in accordance with the invention; Fig. 2is a top plan view, showing the manner of arranging the sections of theculvert to break joint; Fig. 3 is a vertical cross sectional view of thesame looking toward the rear side of thc bank retaining plate or wall;Fig. 4 is a porspec-' live view of one of the side sections of theculvert; Fig. 5 is a similar view of the opposite side section; Fig. 6is a similar view of the bottom section; Fig. 7 is a detail sectionalview through a portion of one end of the culvert and the bank retainingwall, showing the manner ol' (miner-ting these parts together.

ltoforring more particularly to the drawings, 1 denotes the culvert,which consists ofja base section or bottom 2 having on its opposite sideedges upwardlyprojecting flanges 3, in which are arrangedlongitudinally-disposed grooves or channels 4-. p The upper portion ofthe culvert is formed by side sections 5 and, 6, which curve inwardly attheir upper edges and overlap to form the top of the culvert. "he upperedge of the side section 5 is provided with an offset overhangingprojection 7, which engages the upper side of the adjacent edge. of thesection (5, said upper end of the sec-.

lion U fitting into the offset portion of the section 5, as shown. Thelower edges of the side sections 5 and 6 are provided withoutwardly-projeeling langes 8, which are adapted to be engaged with thegrooves or channels 4 in the opposite edges of the'baseseetion 2.

Formed on' the inper side of the base-section 2 adjecting lugs 9, whichare adaptedto engage the adjathe flanges S on the lower edges of thesame into ongageinent with the grooves 4 of the base section. on theinner wall of the side section 5 adjacent to the offset projection 7 isformed a. series of lugs 10 adapted to project beneath and engage theinner face of the op .positeside section 6, when the latter is'inengagement with said offset projection. The lugs 9 and 10 serve toeffectually prevent the collapsing of the sections of the culvert,thereby forming a strong durable construction, which will readily adjustitself to the expansion and contraction of the metal sections, due tothe changes in the weather.

culvert, the sections are arranged to break joint, this beingaccomplished by providing the sections'at each end Fig. 2 of thedrawings.

Adapted to "be used in connection with the culvert retaining walls 12,which preferably consist of a main culvert engaging portion formed oftwo adj usta'bly connected platcslfi, the inner edges of which arerecessed or cut out to 'fit upon the outer surface of the culvert. The.engaging-portions of the plates 13 overlap above and below the-culvert,said overlapping portions being provided with alined slots 14. Throughthe slots 14 are arranged clamping bo ts 15, by means of which theplates are adjustably sci-" ed together. The outer side edges of theplates 13 are bent at an angle to the plates to provide attachingflanges-16, to which are adapted to be bolted or otherwise securedextension plates 17, of which there may be any desired number, saidplates being bolted togethertto form projecting wings, which may be ofany desired length depending upon the number of plates thus securedtogether. The wings formed with respect to the plates 13 forming themain portion of the retaining wall. i

L i angular, rearwardlypro eeting flanges 18 having formed cured to theupper edge of. the main retaining wall, thereby providing for theincrease in the height of the retainin g I wall. There. Jay be anydesired number of the plates 21, the opposite edges of each of which arebent to cent inner side walls of the side sections 5 and to held,

In assembling the base and side sections to form the of the culvert ofunequal length,. as clearly shown in v and secured to one or both endsof the same are bank by the plates 17 may be arranged at any desiredangle The'upper edges of the plates 13 are bent to form right thereinelongated apertures 19 to receive clamping bolts 20, by means of whichtop extension plates 21 are sejacent to the opposite edges thereof areupwardly pro- -l'orrn right angular, rearwardly-projecting.attachingflanges, through which are arranged fastening bolts to secure the platestogether one above the other, thus pro- '13, the attachment of the topplates thereto will not interfere with the lateral adjustment of saidplates 13. The outer ends of each of the end sections of the culvert areprovided with radially-projecting substantially V-shaped flanges 22,with'which are engaged one end of zig-zag or z-shaped clips or fasteningdevices 23. vThe ends of the fastening devices 23 are engaged with theinner edgesof theplates 13 forming thelm'ain "por tion of the wall,therebysecurely: fastening the retain ing wall to'the ends of theculvert. On the innerends of the end sectionsioi the culvert and on theends of each of the intermediate sections are formed radiallyprojectingflanges24.- These flanges 24 are substantially triangular in crosssectionand havefa: fiat or right angular outer surface, said flat right.angular outer sur a face of the adjoining sections being engaged tovform a close connectionjorjoint between said coincident or adjoiningsection; I .7

From'the foregoing description, taken in connection Yithth accompanyingdrawings, the construction and operation of invention will be readilyunderstood without requiring a more extended explanation. 1 .Variouschanges in the form, proportion and'the mi nor details of constructionmay be resorted to without departing fro n the principle or sacrificinganyoi the adclaims.

Having thus described our invention, What we claim as new'and desire tosecure by Letters-Patent, is:

plates.

and in which the latter fits; said wall beingarranged to bear againstthe flange and'c onsisting of a pair of'plates just ably connecting theplates,' right angularly disposed 'right-angularly' disposed'iian'gesand provided with slots,

the extension plate to thewnli, and substantially Z-shaped clips havingtheir end portions engaged respectively with the end flangeof theculvert and'withithe inner edge of the retaining wall. i
